Three types of the photomechanical effects have been studied in BaTiO3 and PbTiO3 like crystals subjected to local mechanical stresses, namely, the photodomain effect, photomechanical effect and photo-mechanic-ferroelectric effect. All the effects studied are rooted in the interaction of the released current photocarriers with various microstructural elements of the crystal, i.e. the 90-domain walls, dislocations and cracks being formed.
